DANGER Remove hands and feet from beneath the case before the casters are removed. Failure to do so may result in serious injury when the case is lowered. DANGER Once an outrigger have been removed, DO NOT push or attempt to move the case until all remaining outriggers are removed. Doing so may cause the case to tip over, possibly resulting in serious injury or death. DANGER SHOCK HAZARD Always disconnect power to case when servicing or cleaning. Failure to do so may result in serious injury or death.
GENERAL INFORMATION Welcome to the Hill Phoenix display case family. We’re very pleased that you’ve chosen Hill PHOENIX for your food merchandising needs. This handbook is targeted to individuals involved in the installation and/or operation of Hill Phoenix display cases and contains detailed illustrations and important information about the product. By closely following the manual’s instructions, you can expect peak performance, attractive fits and finish, and long case life from the product.
USING OUTRIGGERS Hill Phoenix cases are manufactured and shipped to stores with outriggers installed on the base frame. This ensures that moving the cases is easier for everyone involved in the manufacturing, shipping, and installation processes. Outriggers also reduce the risk of cases being damaged by the raising and lowering of the cases with a ”J” bar when placing them on dollies, skates, or rollers. In most situations, one or two persons can move the case with ease.

INSTALLATION The ONNA-3' is shipped with most of the exterior panels and trim already installed. The only exterior parts that need to be installed when the case arrives are the kickplate and the back lower-panel. For lower back-panel installation, slide the back-panel up under the channels, then use the supplied screws to fasten to the baseframe (see illustration below for details). The kickplate, which is shipped in the case, simply slips upward behind the front panel and then down onto the baseframe.
PLUMBING All of the plumbing components are attached to the case at the factory; therefore, no assembly is required. The case drain is located front-and-center of the cases for convenient access and is made of cast metal. The “P” trap, furnished with the case, is made from PVC pipe. Should any future maintenance issues arise, care should be given to assure that all connections are water-tight and sealed with the appropriate PVC cement and primer.
REFRIGERATION COMPONENTS Access Valve - Access port on the evaporator that allows service personnel to check system pressure. eration system that removes water and other impurities from the refrigerant in the lines during initial start-up. Receiver - The component in a refrigeration system that stores liquid refrigerant that is not being used by the system in low load conditions or when the system is shut down.
REFRIGERATION PIPING The diagram below illustrates all of the refrigeration components in the ONNA-3'. The components surrounded by the box are located in the case tank. Basic definitions of these components are listed on the preceding page. The expansion valve and other controls are located on the left-hand side of the case and are accessible without lifting the fan plenum. The controls cluster may be reached by lifting only the left hand deck pan minimizing the need to unload product.
ELECTRICAL HOOK-UP No in-field wiring is required for installation of the ONNA - 3': all electrical connections have been completed prior to shipping. Simply plug the power chord into an appropriate electrical outlet. The condensate pump is plugged into a receptacle mounted in the junction box, behind the front removable panel (see below). NOTE: the receptacle is intended for use with the drain pump only and not as a power supply for any other equipment.
(Electrical Hook-Up, cont'd) HOW TO ACCESS BALLASTS An electronic ballast operates the case lamp and is located in the electrical junction box behind the front panel. To gain access to the ballast, you must remove the 2 screws on the front of the junction box access panel. The ballast is located on the left side of the junction box (see diagram below). BALLAST BOX JUNCTION BOX ACCESS PANEL DANGER SHOCK HAZARD Always disconnect power to case when servicing or cleaning.
DEFROST & TEMP CONTROL The ONNA uses timed-off defrost as its primary defrost method. Access to the termination control probe can be gained by simply removing the plastic plug in the flu-panel. The temperature control probe is located behind the 3” plug button in the top flue panel (see diagram). Both of these probes are wired to the case controller that is mounted on the top of the case. MODEL ONNA TEMPERATURE CONTROL PROBE LOCATION (behind the 3” plug button).
AIR FLOW & PRODUCT LOADING Cases have been designed to provide maximum product capacity within the refrigerated air envelope. It is important that you DO NOT overload the food product display to avoid impinging on the air flow pattern. Overloading will cause malfunction and the loss of proper temperature levels, particularly when discharge and return air sections are covered. Please keep products within the load-limit lines shown on in the diagram below. MODEL ONNA DISCHARGE................1 LOAD LIMIT...

APPENDIX C: USE & MAINTENANCE
IN- STORE SERVICE FOR ONNA-3 DANGER Electrical Shock Hazard Always disconnect power to case when servicing or cleaning. WARNING HIGH PRESSURESwitch Off Both Power Switches Before Pre-Cleaning Case. 5. Make sure the drain is free of any obstructions. 6. Using only a wet cloth and a bucket of clear water, wipe the case; never use a hose on a Self-Contained case with an evaporative pan. PRE-CLEANING 1. Relocate product to alternate refrigerated storage area, then turn off condensing unit and main power.
IN- STORE SERVICE FOR ONNA-3 WARNING Verify Both Power Switches Are Off Before Cleaning Case. CLEANING 1. Verify that both switches were turned are OFF during pre-cleaning. Both switches are located behind the upper access door. HIGH PRESSURE 6. Spray shelves (starting at top) with a mild cleaning solution. Wipe each shelf (starting at the top,) ensuring that the grove in the tag moldings is thoroughly cleaned. 2. Always clean from the top down. 7.
IN- STORE SERVICE FOR ONNA-3 CAUTION FILTER CHANGING The heating element in the evaporator pan is very hot when on. In store service is limited and can be completed in just a few minutes each week.
